When Will You Learn About the World?

Just like a person who comes to learn medicine cannot do it in spare time -- He can't work all day long and late at night, and spend a little time studying medicine; it won't amount to anything. It's a full day's work for years -- likewise, a person who is busy with everything but [studying his mission in life] is not going to understand anything about the world and about Torah and about the afterlife and about his relationship to his fellow man and his relationship to Hashem. He'll understand nothing at all, because it's something that requires a great deal of thought. -- Illuminating the Mind (#009)
